i have friend that is looking into the use of clenbuterol from acillaryguys. my question is how fast would he get the product, and i would like to hear of any personal past experiences. he has a low resting heart rate, would this be a problem if he used clen? thanks in advance. if there is any doubt that there could be some complications because of the slow resting heart rate i will advise him not to take it. thanks again.
